Rudest till operator ever with bad attitude

I was assisted by the rude till operator her name is Chumisa on the 02 December 2020 , I requested the price on the item that was on special then she just ignored me and never rep****. I repeated myself before I buy the item if it still on sale ,she just took the items scan and put in the bag and kept quite standing. I have to assume that I must put the card on the machine , she did not say anything when requesting the price and when I was done with purchasing she just throw the slip on my bag. I even asked her are you not able to speak and she just stare at me with funny look.
